It's basically supported by me now :-).

OpenJDK-8 definitely builds on PowerPC32. I'm not exactly about the
additional patches at the moment though. The Debian package currently
carries these patches:

However, Debian has u151. Depending on what got backported in the
meantime, you might need this patch:

It might also depend on the gcc version whether this patch is needed.

Either way, a build log will be very helpful for debugging this.

Thanks,
Adrian
